RESUMO
BACKGROUND: Sporotrichosis is a fungal disease caused by the Sporothrix schenckii species complex. It is usually acquired by trauma with plants. Lymphatic-cutaneous is the most common clinical manifestation. CASE REPORT: The present case describes the development of an epidermoid carcinoma as a late complication on a long evolution sporotrichosis scar. During a period of 50 years, the patient had lesions in the right hand. Sporotrichosis was diagnosed and treated with potassium iodide. Eleven years after the healing of the lesions, a squamous cell carcinoma on the scar of this mycosis was diagnosed. CONCLUSIONS: The chronic sporotrichosis injury was probably the cause of the tumor developed on the scar.

Nontuberculous mycobacteria are etiologic agents of opportunistic human infections. Although they usually affect superficial tissues, infections in bones and joints have been described. The contamination is associated with increased environmental exposure. With appropriate therapy, the cases usually progress to complete recovery of the patient. This study reports the case of a patient who developed a cutaneous nodule in her left foot acquired when her skin was punctured by a fish. The anatomopathological examination revealed chronic central suppurative granulomatous dermo-hypodermal inflammation. Furthermore, the screening for resistant acid-fast bacilli was positive.
Micobactérias não tuberculosas são agentes causadores de infecções oportunistas no homem. Embora, geralmente, afetem tecidos superficiais, infecções em ossos e articulações têm sido descritas. O contágio está associado ao aumento da exposição do homem ao meio ambiente. Diante da terapêutica adequada, os casos normalmente evoluem com recuperação total do indivíduo. Este estudo descreve o caso clínico de um paciente que apresentou nódulo cutâneo no pé esquerdo após traumatismo com um peixe. O exame anatomopatológico revelou inflamação crônica granulomatosa centralmente supurativa dermo-hipodérmica e a pesquisa de bacilos álcool-ácido resistentes (BAAR) foi positiva.
